About CD9
The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra-and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This full transporter is a member of the MRP subfamily which is involved in multi-drug resistance. This protein functions as a multispecific organic anion transporter, with oxidized glutatione, cysteinyl leukotrienes, and activated aflatoxin B1 as substrates. This protein also transports glucuronides and sulfate conjugates of steroid hormones and bile salts. Alternatively spliced variants of this gene have been described but their full-length nature is unknown. [provided by RefSeq, Apr 2012]

About Brilliant Violet 650
Brilliant™ Violet 650 (BV650) is a red-emitting tandem fluorophore that can be excited by the 405 nm Violet laser and collected using a 660/20 bandpass filter. BV650 has an excitation peak at 405 nm and an emission peak at 645 nm. Due to its unique Stokes shift, not many dyes have identical excitation and emission spectrums, but the nearest alternatives include SuperBright 645, Qdot® 655 and eFluor™ 650NC (ThermoFisher). BV650 exhibits a medium level of brightness and is most often used in flow cytometry, specifically, it is an alternative to nanocrystals used for intracellular flow. This dye is part of the Brilliant™ Violet dye line of fluorescent polymers. Brilliant™ Violet 421 polymer is employed as the donor molecule in a series of tandem dyes with acceptor molecules emitting at various points across the visible light spectrum. The Brilliant™ Violet dyes are a superior alternative to QDot nanocrystals and similar to SuperNova dye from Beckman Coulter and StarBright dyes from Bio-Rad.
